.MIXER FOR GAS-ENGNES Specification of Letters Patent.

raienteu oet.'` inviare.

Application medium: 28, 191'6. Serial No. 106,525.

especially designed to Irake use of the heat' generated in the exhaust manifold for converting water into steam and also for heating air, with means for Conveying a mixture lof steam and hot air into the intake manifold. of an engine, whereby to increase the eiiiciency of the engine, especially under speed. This mixture of hot air and steam in the engine, while it makes a thinner explosive mixture, keeps the engine clean of carbon and also makes possible more mileage per" gallon of gasolene or distillate, which ever may be used, under speed.

My invention is attached as an'auxiliary feature to the engine and can be controlled `by any suitable lever mechanism placed within convenient reach' of the operator. When the engine is running slowly the usual mixture from .the carbureter only 1s used, but under spe ed'with the use of my steam and hot air mixer, greatly increased mileage can be secured.

-My in `rention is readily adapted to any gas or internal combustion engine without material change or reconstruction thereof.

In order that others may more fully understand by invention I have illustrated one practical embodiment thereof in the ac companying sheet of drawings, which I will -now describe. i

Figure l is a top plan view of my invention as applied to the exhaust pipe, or inanifold` of an engine; and

Fig. 12 is a side elevation thereof, partly in section to show the interior construction and arrangement. l

Referring now more in detail to the drawings, E designates the exhaust manifold, or pipe, of a gas engine; I designates a fragmentary portion of the intake manifold.

My invention as here illustrated, coin prises a metal box, or case, 1, adapted to be clamped against theexhaust manifold, or exhaust pipe, by means of clamp members 2-2, as indicated, whereby tiie heat from said exhaust pipe or manifold heats said box, or casing. A perforated partition member 5, is mounted across the middle of said box, or casing, as indicated in Fig. 2. A water pipe 4, from the water rircuhiting system of the engine, is connected into the bottoni of said box, or casing. 1. as at 53. Valve mechanism t3, within the box, or casing, 1, controls the inlet of water into the lower part of the box, or casing, as will be -eleai'ly understood from Fig. 2 of the drawings, The details of this need' not be de scribed as any .oat valve mechanism may be used which will perform the function of controlling the inflow of water-and maintaining it at a desired depth.

A hood, 7, is also formed over the eX- haust pipe, or manifold il, as here shown,

immediately above the box, or casing, l.

The' object of said hood is to gather heated air around the exhaust manifoid. A pipe 8, is connected with said hood, as at 9, and

is also connected to the box, or casing, '1, above the perforated partition 3, as at l0. A pipe 11, is connected, as at 12, with the .top of said box, or casing, l, and at its opposite end is connected with a needle valve mechanism 13, connected to the intake manifold I, clearly indicated in Fig. 2, said needle valve mechanism being operated by y a bell crank 121, with which is connected an operating rod, or wire, 15, which may be extended to any convenient position fortlie operator. y

Within the box, or casing, 1above the per-l forated partition 3, is a three-way check valve member 16. Steam which has been ,generated in the lower part of the b ox, or casing, 1, passes into the upper part thereof through the perforated partition 3. The

check valve memberil, is provided with a' ball valve 17, at. its connection with the pipe '8, whereby hot air from' the hood 7, can vbe drawn into said check valve member, but back flow ispreveted. Said check Valve Amember'is also provided with a ball Valve 1.8, Whichpermits the steam to b e drawn .into said check valve -meinber and up through the pipe 11, but prevents back flow into the box, or casing, 1. Thus it will be clear from the drawing, that hot air from the hood 7, through the pipe 8', and steam from the upper .part of th'e box,'or easing, 1, can be drawn through the pipe 1l, and

through the needle valve '13, into the intele manifold I, wheneler said needle valve is Opened through the operating rod 15.

The partition member 3, in the box, or casing, prevents splashing of the water in .the lower part of the box, or easing, l, and at the same time limits the movement of the float valve 6. The float valve, of course automatically regulates` the amount of water admitted to the box, or casing, l, from the water circulating; system of the engine.I

The box, or easing, l, is also pro'uided with l e, puppet valve, 19, for the escape of steam therefrom in case the steam pressure should become sullieient to open said puppet valve.

am ewarethat many changes in details can be made in my invention as here shown for purposes of illustration, without departing from the spirit thereof, and I do not, therefore, limit the invention to the particular ehovvingf1 made, except as I may be' limited by the ereto appended claim forming a part thereof.

I claim:

In combination with an internal eombuetion engine end the exhaust and'intake members thereof, a water 'box mounted on lQaid exhaust member and having therein a water chamber and a steam chamber thereabove, with a perforated wall therebetween, valve-controlled water supply connect-ions from said water 'chamber to the water oirculating system of said engine, a Supply pipe from theeteam chamber of Said box to said intale member, a hot air pipe provided with means for taking heated air from around seid exhaust member and connected with said steam supply pipe leading to said intake member, and ball-check valves controlling the passage of steam and hot air through said steam and air supply pipe and preventing,r flow of steam back through l said hot -air pipe, said ball-valves being' moved to open the passagways controlled by them by the suction through said pipes, and automatically oy'ierating by gravity to close said passageways, substantial] y as describml.
